1. How do I warm up a new mailbox?
SkySenders does not offer warmup. You should start with low-volume sending (10–20 emails/day) and gradually increase, or use third-party warmup tools like Mailwarm, Warmup Inbox, or Smartlead warmup.
2. What should my cold email avoid to stay out of spam?
Avoid:
Spam trigger words (“free,” “guarantee,” “buy now”)
Large images or attachments
Too many links
Generic or copy-paste messages. Instead, personalize your emails and send to verified contacts.
